CVE-2026-22186

Name of the Vulnerable Software and Affected Versions Bio-Formats versions up to and including 8.3.0

Description Bio-Formats versions up to and including 8.3.0 contain an XML External Entity (XXE) vulnerability in the Leica Microsystems metadata parsing component, such as XLEF. The parser uses an insecurely configured DocumentBuilderFactory when processing Leica XML-based metadata files, allowing external entity expansion and external DTD loading. A crafted metadata file can trigger outbound network requests (SSRF), access local system resources where readable, or cause a denial of service during XML parsing.

Recommendations Versions prior to 8.3.0 should be used.
